High Precision GNSS RTK Solution
 

High Precision GNSS RTK Solution  Overview

MSJ's RTK (Real Time Kinematic) GNSS systems, which supports multiple satellite systems and frequencies, can obtain high accurate position stably and can be widely used for the surveying and the investigation of crustal movement, which centimeter class accuracy must be needed, and the automatic driving of industrial machines.

 

What is RTK (Real Time Kinematic positioning)....

RTK is the method for measuring rover's position in realtime by means of observation corrections which be transmitted from a known position (base station) to the rover through wireless or mobile network. The measuring method which is different from the code phase method which is popular for car navigation or mobile phone is able to get further high-precision position by using carrier phase and observation correction. Additionally, Increasing visible satellites by supporting not only GPS but also other satellite systems
contributes to better stable positioning. RTK system which can provide centimeter class accuracy is growing in popularity for not only survey purpose but also for automatic operation for agricultural machine or construction machine.
